BOTTLE AND CAP-FASTENER 1,132,1ldO.

Specification of Letters Patent. Patented Mar. 16 1915.

Application filed June 1, 1912. Serial No. 701,011.

Fasteners, of which the following is a specification.

This invention relates generally to bottle caps, and more particularlyto the means for fastening said caps upon the necks of bottles, theobject of the invention being to provide a cheap, simple and efiicientmeans for quickly and easily securing the cap, which means can bereleased when desired and used again and again as required for refittingthe caps upon the bottles.

With these various objects in view my invention consists of the novelfeatures of construction hereinafter fully described, pointed out in theclaims, and shown in the accompanying drawings in which,

Figure l is a perspective view showing the up er end of a bottle neckprovided with a cap fiistened by one form of my improved fasteningmeans. Fig. 2 is a front elevation of a bottle neck and cap, said capbeing fastened by a slightly different form of fastening means. Fig. 3is a detail sectional view taken on the line 33 of Fig. 2. Fig. 4 is aview showing a bottle cap fastened by a slightly different form offastener. Fig. 5 is a detail perspective view of said fastener detached,while, Fig. 6 shows a still further modified form of fastening device.

Referring to the drawings A, indicates a cap having a slotted skirtcarrying a spring ring B, the ends of said ring being carried past eachother and bent to provide hooks as shown at B, and between theseoverlapping hooked ends I introduce a fastening wedge C, which may beeither solid or skeleton form and adjacent its wide end is formed withnotches or recesses C, so that when the said fastening wedge is forceddown the spring ring B, will be tightened thereby clamping the cap uponthe neck of u the bottle and this downward movement is clearly shown inFigs. 2 and 3. These hooked ends are engaged by means of a fasteningwedge E, which is in the form of a plate having its side edges rolledover as shown at E, so as to engage the hooked ends D,

i and by forcing this wedge E, downwardly,

it is obvious that the ends of the spring ring are drawn togetherthereby clamping the skirt of the cap firmly upon the end of the bottle,and adjacent the narrow end of the wedge, recesses or depressions E areprovided into which the hooked ends of the wire ring seat themselveswhen the locking operation is completed. In this particular structure,the fasteningoperation is accomplished by forcing the tapering frame orskeleton wedge downwardly so as to contract the spring ring and therebyfasten the skirt of the cap upon the neck of the bottle.

In Fig. 6, I have shown another form of fastening device G, which is inthe form of an oval shaped link having notches or recesses G, adiacentits upper end and in practice this link is placed over the hooked endsof the spring ring and is given a movement at right angles to the planeof the fastening ring so as to bring the hooked ends D, into engagementwith the notches or recesses G, and the link G, as well as all ofthe'other forms of fastening devices will of course rest against theexterior of the neck of the bottle in its fastened position. and inpractice. I prefer to employ a pro tecting collar H, upon the exteriorof the bottle neck and at a point below the lower end of the fasteningdevice, said collar serving to prevent the accidental upward dislocationof the fastening device after the same has once been fastened orsecured. Furthermore, a sealing band may be wrapped around the neck ofthe bottle and the fastening device. and secured to said parts in orderto insure the genuineness of the contents of the bottle.

It will be seen that in all of the various forms herein shown anddescribed, the contraction of the spring ring for the purpose ofcontracting the cap is accomplished by means of a fastening wedge whichmoves in a plane at right angles to the plane of the ring and in suchmovement draws or forces the ends of the ring together, therebycontracting sald ring and clamping the cap upon the neck of the bottle.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is:

1. The combination with a bottle having a cap comprising an elasticskirt and. a contractile ring, said ring having hooked end portions, ofa taperin locking device ada ted to engage said ooked rmg ends, sailocking device being movable bodily in a plane arallel at all times tothe bottle neck, sai movement in one direction contracting the ring andin the opposite direction expanding the ring.

2 A cap having an exp'ansible and contractible skirt and carrying a ringprovided with hooked ends, a wedge shaped 15 fastening device arrangedfor en agement with said hooked ends and adapte to move at right anglesto the plane of said ring for r the purpose of contracting the same,said fastening device bein provided with seats 20 for receiving the hooed ends of the'rin when the fastening dance is in its locke position, assetforth. r
